BACKGROUND: Repair of complete atrioventricular canal (CAVC) with tetralogy of Fallot (TOF) is a challenging operation increasingly being performed as a complete, primary repair in infancy. Previous studies have focused on perioperative outcomes; however, midterm valve function, ventricular function, and residual obstruction have received little attention. METHODS: We retrospectively reviewed 20 patients who underwent CAVC/TOF repair (January 2005 to December 2014)...

OBJECTIVES: Severe cases of infective endocarditis (IE) of the aortic valve can cause aortic root destruction and affect the surrounding structures, including the aortic-mitral continuity, the anterior mitral valve leaflet and the roof of the left atrium. Reconstruction after resection of all infected tissue remains challenging. We describe our surgical approach and the mid-term results. METHODS: Between January 2004 and December 2015, 35 patients underwent surgery for extensive IE of the aortic valve with destruction of the aortic root, the aortic-mitral continuity and the mitral valve...

OBJECTIVES: Valve-sparing operations and root replacement with a biologic composite conduit are viable options in aortic root aneurysm. This study was conceived to compare the early and mid-term results of these 2 procedures. METHODS: From September 2002 to November 2015, 749 consecutive patients underwent either a valve-sparing operation or a root replacement with a biologic composite conduit at 2 institutions. Propensity score matching was used to compare similar cohorts of patients in the overall population and in the ≤ 55 and ≥ 65-year age groups...

Both aortic valve commissural detachment and commissural fenestration are rare causes of aortic regurgitation. In general, aortic valve replacement is the mainstay treatment for aortic regurgitation caused by commissural detachment or commissural fenestration. We herein describe valve-sparing aortic root re-implantation and aortic valve repair for aortic regurgitation and aortic root dilatation in an extremely rare case accompanied by both commissural detachment and commissural fibrous strand of fenestrated cusp...

Valve-sparing aortic root reconstruction is an up- and-coming approach for patients suffering from aortic valve insufficiencies which promises to significantly reduce complications. However, the success of the treatment strongly depends on the challenging task of choosing the correct size of the prosthesis, for which, up to now, surgeons solely have to rely on their experience. Here, we present a novel machine learning based approach, which might make it possible to predict the size of the prosthesis from pre-operatively acquired ultrasound images...

OBJECTIVE: We describe a simple method to assess the aortic valve using a videoscope inserted in the left ventricle (LV-VS) during valve-sparing root replacement. The aim of this study was to evaluate the feasibility of this technique by comparing it with the findings of postoperative transesophageal echocardiography (TEE). METHODS: Thirty-six patients (29 male, mean age 45.4 ± 20.1 years) undergoing aortic root reimplantation were assessed intraoperatively with LV-VS...

Background evidence-based medicine (EBM) approaches have reached broad acceptance, both in conservative and surgical disciplines. The aim of this study is to clarify the role of EBM in a rare condition of aortic regurgitation (AR) with surgical indication. Methods A purpose-built Internet-based questionnaire was sent to 607 cardiovascular surgeons in Germany, Austria, and Switzerland. A virtual 64-year-old patient's medical history was presented, including two ultrasound images and one computed tomography scan, showing a 58-mm aortic root aneurysm and a severe trileaflet regurgitant aortic valve...

OBJECTIVES: If the aortic root dilates after native aortic valve-sparing root reconstruction with remodeling, aortic regurgitation may recur. However, it has not been demonstrated clearly that the aortic root dilates after remodeling. METHODS: This study enrolled 15 patients who underwent an aortic valve-sparing operation with remodeling (2002-2014) but without any ventriculo-aortic junction (VAJ) fixation. Technically, special care was taken to pass the sutures through the fibrous annulus...

OBJECTIVE: Although the remodeling technique provides the most dynamic valve-sparing root replacement, a dilated annulus (>25 mm) is a risk factor for failure. Aortic annuloplasty aims to reduce the annulus diameter, thus increasing coaptation height to protect the repair. The results of 177 patients with remodeling and external aortic ring annuloplasty were studied. METHODS: Data were collected from the Aortic Valve repair InternATiOnal Registry. Preoperative aortic insufficiency grade 3 or greater was present in 79 patients (44...

OBJECTIVE: Advancements in cardiothoracic surgery prompted investigation into changes in operative management for acute type A aortic dissections over time. METHODS: One thousand seven hundred thirty-two patients undergoing surgery for type A aortic dissection were identified from the International Registry of Acute Aortic Dissection Interventional Cohort Database. Patients were divided into time tertiles (T) (T1: 1996-2003, T2: 2004-2010, and T3: 2011-2016). RESULTS: Frequency of valve sparing procures increased (T1: 3...

OBJECTIVES: In patients with acute aortic dissection involving the arch and the descending aorta (AADA DeBakey type I), performing a total aortic arch replacement with the frozen elephant trunk (FET) procedure for supposedly better long-term results is still controversial. METHODS: From February 2004 to April 2016, 94 patients with AADA DeBakey type I had an FET procedure (80% men, age 58 ± 12 years). During the early period (Group 1, 2004-10), the FET technique was performed using non-branched grafts...

Sinus of Valsalva aneurysms are rare cardiac abnormalities that may be congenital or acquired. Patch closure or direct closure of the aneurysm orifice is a frequently performed surgical repair strategy. In this report, we present a rare case of an isolated giant right sinus of Valsalva aneurysm with aortic insufficiency and right coronary artery obstruction. We treated this patient by a valve-sparing aortic root remodelling procedure with partial preservation of the intact Valsalva sinuses and coronary artery bypass grafting with a favourable outcome...

There is evidence that high surgical volume and team consistency improve outcomes. Mortality of 4%-12% for aortic root surgery has been reported in the United States and UK. We aim to assess outcomes of patients undergoing aortic root surgery by a consistent, high-volume team. Data on patients undergoing elective or urgent aortic root replacement (ARR) were collected prospectively. Patients undergoing emergency surgery were excluded. A standardized perioperative approach was maintained and was achieved by delivering training to team members, including surgical trainees, anesthetic, nursing, and perfusion staff, whenever there was a change of team...

Valve-sparing aortic root replacement remains challenging for patients with eccentric severe aortic regurgitation when the cusps are totally asymmetric. We report a case of successful reimplantation operation for such a lesion. Because free margin lengths from commissure to Arantius body of the adjacent two cusps were matched while inter-commissural distances were totally different, right coronary cusp prolapse was corrected by asymmetrically aligning the position and height of three commissures without cusp plication...

Transcatheter aortic valve implantation (TAVI) is an emerging treatment for high-risk patients with aortic stenosis. Aortic regurgitation is considered to be a relative contraindication for transcatheter procedures, as a non-calcified aortic annulus poses the risk of an insufficient anchoring of the transcatheter aortic valve prosthesis. Herein is described the case of a patient who suffered from recurrent aortic valve regurgitation after valve-sparing repair, and which was successfully treated by the transcatheter implantation of an Edwards SAPIEN 3™ prosthesis...

REVIEW
Emile Bacha
This review deals with a relatively new field in congenital heart surgery, valve preservation or, in cases of more severe pulmonary valve stenosis or dysplasia, valve reconstruction during tetralogy of Fallot repair. We describe the stepwise approach utilized, starting with simple maneuvers such as commissurotomy and valve dilation for mild pulmonary stenosis to commissurotomy and intraoperative balloon dilation for moderate stenosis, and finally transection of the annulus and valve reconstruction using a patch that acts as a modified monocusp...
